Forgot to post the final tune. After all the waiting, the end result is a little disappointing, expected a bit more grunt, but not over yet, a few things to sort out .

Going to beef up the fuel and exhaust.

Flex tune and see how it goes.

currently on its run in tune, 288kw @ 17psi and only reving to 6k rpm on bp98

UPDATE...

After the engine was ran in I strapped it down again which it made 320kw on 20 psi, and having iat problems.

I then fit a new plazmaman intercooler and ran it on the dyno with pump e85 making 374kw on 21psi, which is all the little t67 will do.

Balanced Blah blah

375rwkw @ 17 psi BP 98 (369 for the track)

[Pezhead]

Very similar build spec and result to acsplit above.

My goals are for a responsive track car I can daily on 98 - drive and fill up anywhere.

RB30 Bottom end w/ Ross Racing Pistons & Spool forged rods

Garrett 2860 -5 Twin Turbos

Tomei Expreme Dumps

Low comp 7.85:1 (to keep things safe on 98, YES I'm staying 98 for a while)

ARP M11 Head Studs

Nismo 0.9mm Metal Head Gasket

+1mm Supertech valves with Supertech springs & retainers

Tomei Pro Cams 260 10.25mm lift

ID 1000 injectors

Autronic SMC / 500R CDI (Super Old School!) firing through Splitfire coils

Adj cam gears

Nitto Oil Pump

Single 044 pump & 2L surge tank

[Pezhead]

Here is the torque curve. Modest, but I wanted that to try to keep my stock gearbox alive. Nice and flat though

[whatsisname]

Had the car on the dyno today.

Still early stages at the moment. Just finished running-in new the RB25/30DET. Timing and fuel is conservative, purely as we ran out of time in the day to make improvements.

A quick power run on 22psi (E85) resulted in the following:

411kW at wheels on just shy of 20psi

428.8kW at 22psi

Aiming to run up to 30psi

[Nismo 3.2ish]

Just leaving the final Dyno to finish my tuning experience

98 pump@ 22psi = 437kw

E85 @ 22 psi = 462kw

E85 @ 25.5 = 475kw

Other Dyno is overlay of old tune 98 pump 367kw @ 22psi and new tune on 98 pump 437kw @ 22psi

Update

Decided to go V-Cam

Lost a little up top, but it the injectors and Turbo were just about maxed, all good

The end, I hope
